ABSTRACT:
The invention provides a separator for removing small particulates from an air stream, the separator includes pneumatic separator with a relatively small filter element built inside the separator to remove particulates from the air stream down to as small as one micron. The pneumatic separator relies on a vortex effect and sudden changes in direction of the air flow to strip out most of the particulates, and because the very small particulates have insufficient mass to be dislodged from the air in this way, these particulates remain in the air stream and are carried to the filter element where they build up on the element. The build up is interrupted by the incoming air which flows aggressively around the element and strips parts of the build-up off the element. This ongoing random process can be supplemented if necessary by back flushing. Both the separated particulates and those stripped off the filter element accumulate in the separator for subsequent removal.
